We look at the division of 869179 by 87 
Let's see how many times 87 fits into 869179.

Going ahead to step 1:
87 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 87

Let's proceed to step 2:
If we divide 86 by 87, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 87

Advancing to step 3:
87 goes into 869 9 times with a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 783 from 869 to get 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 87

Going ahead to step 4:
When dividing 861 by 87, we get 9 with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Deduct 783 from 861 and we're left with 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 87

Going ahead to step 5:
The number 87 fits into 787 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 999.0
Deduct 783 from 787 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 87

Moving on to step 6:
The number 87 fits into 49 0 times, leaving a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 9990.0
If we subtract 0 from 49, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
When dividing 490 by 87, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 9990.5
The remainder is 55 after subtracting 435 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 8:
550 divided by 87 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 9990.56
Deduct 522 from 550 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
When dividing 280 by 87, we get 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 9990.563
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
87 can be fit into 190 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 9990.5632
Subtracting 174 from 190 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
87 can be fit into 160 1 times, resulting in a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 9990.56321
If we subtract 87 from 160, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 12:
730 divided by 87 is 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 9990.563218
The remainder is 34 after subtracting 696 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
87 can be fit into 340 3 times, resulting in a remainder of 79.
The next digit of our result is 3. 
Result so far: 9990.5632183
If we take 261 away from 340, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 14:
87 can be fit into 790 9 times, resulting in a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 9990.56321839
Subtract 783 from 790 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 9990.56321839 with a remaining 7e-09.
